Retrieving/Updating Document Library Item properties

[sperry1625]

I have a flow that needs to retrieve file properties and also update those properties. Using the built in actions, I can do this without a problem. The flow I have is more dynamic, the Library and the item it needs to update will vary.  I am looking for samples of how to perform a Get File Properties and Update File Properties action except via a SharePoint HTTP call.  For the read, once I make the call how do I access the output? For the update, I am updating a Choice Column.

Any help/assistance/guidance would be greatly appreciated.

Thank you.

I am trying to do something similar, creating files in libraries, where the library name is dynamic in the Flow, using a variable. If I select a library name from the dropdown menu, the library columns, like Title, appear, but when using the dynamic library name:  /variablelibrary name  The columns do not appear. I suppose since Flow doesn't know what library is being referenced until it runs, it has no way of knowing which columns to display, although Title is generic to all libraries.
